Application med March 1s, 1905. serial No. 250,707.

To all whom it mayconecr:

Be it known'that I, FRANCIS MARTIN, -a

,l citizen of the United States, residing at 2432 Polk street, in the city of San Francisco,

county of San Francisco, and State of Caliy fornia, have invented certain new and useful by declare the followin Vand exact descri tion o the said invention, `such as will enab e others skilled in the art to Improvements in Mattresses; and I do hereunder the occu ant.

The drawing 1s a perspective viewlofa mattress constructed in accordance with this invention and applied to an ordinary type of bedstead.

In detail the construction consists of the rectangular frame A, preferably constructed of angle-iron well braced at the corners and stiffened by the transverse brace A', extending across between the side rails of the frame to give added stiHness thereto. The surface of the mattress consists of the rectangular inflexible .top B, composed of interlaced 'wirenetting secured within a sti frame, which/is supported within the frame A by the coilsprings B extending inward from the inner .edges of lthe frame A to the frame of the top B, which gives a` gentle 'resiliency tothe matv tress-top.

It is very essential in a mattress, particularly when occupied by two persons, that the plane ofthe mattress-top be maintained to avoid the tendency to roll the occupants together or apart, .as the case may be. It is also very uncomfortable to yhave a mattress give unevenly under the weight of the occupant. If the mattress ives like a hammock,

it throws too much of t e weight ofthe body on the low point, congesting the blood circulation and often in the case of bedridden inva-`- lids resulting in great discomfort'and bedsores. In the course. of time a-iiexible mattress becomes so strained in places it is impossible to dress the bed tidily. f The particular Specification of Letters Patent.

to be afull, clear, v

' advanta ek of this invent-ion is the fact that the who e mattress-surface is uniformly rewithout disturbing his equipoise.

The yframe A is supported by 'four or `more supports C, engaging the side rails X of the bedstead X. The sup Orts consist Vof fiat stri s of iron havin -thelorizontal surface C an thedownward y-extending legs C2. The ends of these legs are split, one portion being bent horizontal to form the foot C? the unb ent portion acting as a guide against the inner edge of the side rail X to prevent dislodgframe A are rovided with the vertical wooden guides 4, which are securely bolted by the bolts C5 to the frame, of which they are made a fixed part. These guides()4 exface C of the sup Orts, within which they freely move vertica ly, disengagement being prevented by the washer and nut C6. It will also be noted thatby securing the guides in the supports by means of the nut and washer for lconvenience in transportation or for replacing the s rings in the event they become damaged or roken.v v i The weight of the mattress is supported by the expanded coil-springs C7, encircling the 4guides C4 betweenthe mattress-frame and the supports. The guides are preferably made of wood to prevent squeaking ofthe spring as it is expanded and contracted by the,v varying weight on the mattress.,

- A bed provided with this mattress is made up in the usual'manner, someof the advantages being the convenience in tucking in the vsupports being removed from `theextreme ends of the mattress. The mattress being a skeleton framework permits a free circulation right or lies prone on this mattress it maintains its even plane, aside from a gentle resilient accommodation to the movements ofthe occupant. Because ofthe construction this mattress is light, clean, cheap, noiseless, and hygiemc. I

' Having thus described this invention, what is claimed, and desired to -secure by Letters Patent, is-

C- the same may be readily removed eitherv silient vertically, supporting the occupant ment of the 4support C. lh'e side rails of the tend through openings in the horizontal surbedclothing at 'head and footbe'cause'of the i of air thereabout, making it healthful and j sanitary. Whether the occupant stands up- IOO l 1. A device of the character described comi prising a frame, an inflexible mattress resiliently supported within said frame, guides rigidly secured to said frame, truss-like supports provided with depending split legs enoraging the rail of the bed, springs interposed between said trusses and frame, and means for removably securing said guides to said trusses. A

2. A device of the character described comprising a frame, an inflexible mattress resiliently supported within said frame by coilsprings, trusses supported by the rail of. t

on the rail of the bed, said supports being provided with openings to receive said guides, springs interposed between said supports and frame, and nuts upon the ends of said guides to removably secure them in the` openings in said supports.

4. A device ofthe character described comprising a frame, an inilexible mattress resiliently supported within said frame by coilsprings, supports for said frame, each support consisting of a horizontal portion having an opening formed therein and two legs each havin@r a split portion adapted to rest upon the rail of the bed, guides rigidly secured to said frame and adapted to pass through the openings in said supports, springs interposed between said supports and said frame, and nuts upon the ends of said guides to removably secure said l'rame to said supports.

In testimony whereof l have hereunto set my hand this 20th day of February, 1.905.
